通过函数计算的Custom Runtime + HTTP Trigger的方式，可以将F#的ASP.NETCore项目一键迁移，并可直接使用浏览器或者curl等HTTP客户端工具访问函数。
步骤一：准备环境
安装Funcraft，最简单的方式就是直接下载可执行的二进制文件。
- 安装Funcraft到本机。详情请参见安装Funcraft。
- 执行
fun --version检查安装是否成功。
- 执行
fun config配置Funcraft。然后按照提示依次配置Account ID、Access Key ID、Access Key Secret、Default region name。fun config
Aliyun Account ID 1234xxx
Aliyun Access Key ID xxxx
Aliyun Access Key Secret xxxx
Default region name cn-xxxx
The timeout in seconds for each SDK client invoking 300
The maximum number of retries for each SDK client 5
Allow to anonynously report usage statistics to improve the tool over time? (Y/n)
步骤二：部署和调用函数
- 执行以下命令克隆示例工程到本地。
git clone https://github.com/awesome-fc/fc-custom-demo
- 执行以下命令进入克隆的示例项目中。
cd fc-custom-demo
cd FSharp-demo
- 执行以下命令部署函数。
make deploy
执行结果如下。
docker run -it -v $(pwd):/tmp mcr.microsoft.com/dotnet/core/sdk:3.1 bash -c "cd /tmp/FSharpDemo && dotnet publish -r linux-x64 -c Release --self-contained true && cd /tmp/FSharpDemo/bin/Release/netcoreapp3.1/linux-x64/publish && mv FSharpDemo bootstrap && chmod +x bootstrap"

Waiting for service fsharp_demo to be deployed...
Waiting for function fc_fsharp to be deployed...
Waiting for packaging function fc_fsharp code...
The function fc_fsharp has been packaged. A total of 338 files were compressed and the final size was 39.3 MB
Waiting for HTTP trigger http_t to be deployed...
triggerName: http_t
methods: [ 'GET', 'POST', 'PUT', 'DELETE' ]
url: https://19861144305****.cn-hangzhou.fc.aliyuncs.com/2016-08-15/proxy/fsharp_demo/fc_fsharp/
Http Trigger will forcefully add a 'Content-Disposition: attachment' field to the response header, which cannot be overwritten
and will cause the response to be downloaded as an attachment in the browser. This issue can be avoided by using CustomDomain.
trigger http_t deploy success
function fc_fsharp deploy success
service fsharp_demo deploy success
Detect 'DomainName:Auto' of custom domain 'my_domain'
Fun will reuse the temporary domain 16225220-19861144****.test.functioncompute.com, expired at 2020-04-17 10:07:00, limited by 1000 per day.
Waiting for custom domain my_domain to be deployed...
custom domain my_domain deploy success
- 执行以下命令调用部署的函数。
在该示例中，直接通过curl或浏览器访问部署成功后输出的临时域名16225220-198611443****.test.functioncompute.com。
curl 16225220-1986114430****.test.functioncompute.com/weatherforecast
执行结果如下。
